Lifetime arguments are completely ignored in method calls

[petrochenkov]

This snippet successfully compiles despite f not having lifetime parameters and even 'a, 'b, 'c being non-existent.

struct S;

impl S {
    fn f(self) {}   
}

fn main() {
    S.f::<'a, 'b, 'c>();
}

The parser parses lifetime arguments, but doesn't store them anywhere, so they don't present in AST/HIR.
The issue exists since Rust 1.0.

[petrochenkov]

Supposedly they should be stored and then treated exactly like arguments in the UFCS form S::f::<'a, 'b, 'c>.
